Abstract

The effects of drip irrigated fertilization on tea yields, quality and soil character on three different nitrogen(N) application treatments (450βkg/hm2, 300βkg/hm2, 150βkg/hm2)were conducted and by using the conventional fertilization as the control. The results showed that compared with the control, drip irigated fertilization increased tea production significantly by 3.4%~9.3%, it showed a positive correlation between nitrogen application rate and tea yields, a higher production was obtained in the treatment of annual nitrogen input of 300~450βkg/hm2 the drop irigated fertilization showed a insignificant impact on the tea quality. As mature leaf nitrogen content is concerned, drip irrigated fertilization treatment were significantly higher than control, indicating use efficiency of nitrogen fertilizer was higher than that of control, nitrogen content of mature leaf with significant seasonal variations, the highest in autumn tea, summer tea the second, spring tea the minimum. The drip irrigated fertilization promoted the absorption and utilization of nitrogen for tea plant. Different fertilization treatments effected on soil pH significantly, soil pH in drip irrigated fertilization treatment was higher than that of control, probably that the higher nitrogen utilization is helpful in weakening the soil acidification caused by in organic nitrogen.
